$169 million came from other departments, like FEMA and the Coast Guard. The other $33 million came from other areas within ICE.
Many people have made a big deal of this, but please note:
The department has the authority to move funds around internally with the approval of Congress and transfers are not unusual.
This sounds like a lot of money, but is a minuscule part (less than a third of one percent) of the total budget of Homeland Security, which is $65 billion.
